Multidimensional observation technology contributes toward observing cell-cell interactions
Image of 3-D cell observation
In the segment of life science, large number of researches are actively conducted with live cells to reveal roles and functions of proteins or nerves, and pursued for applications in drug discovery or new scientific fields.
Observation at the cellular level allows demonstrating actual functions and roles on genetic information, proteins, nerves or others. Thereby, accumulating knowledge through such researches is one of the key processes to shed light on life phenomena.
Cultured cells have been observed mostly in two-dimensional way. On contrary, a wide variety of cells in living animals or the human body are structured three-dimensionally to form tissues and organs. This implies that understanding the cell to cell interactions in a three-dimensional space is very crucial. The 3D observation technology enables acquiring image data of a 3D cultured-cell specimen being in common ecological environments of humans and animals, analyzing the 3D observation data to visualize cell interactions. With three-dimensional quantitative analysis, it becomes possible to identify all cells in the 3D space and then to analyze the data quantitatively with getting cell population size accurately out of the data.
In addition, the time-lapse imaging, an observation technique to capture a serial of images at regular time intervals, allows investigating time-dependent changes occurring in a cell or cells during the cultivation. Thus, it is very useful to get better understanding of cellular dynamic and activities, as well as cell-cell interactions.
Compared to conventional analyses performed in 2- or 2.5-dimension, 3-dimensional quantitative analysis can recognize the cells in three-dimensional space, which enable to accurately grasp the population for quantitative analysis.
Olympus's optical technology gives higher resolution at a deeper position
To observe a cell, several-tens micrometers in size, on the light microscope, a slight deterioration in light makes a huge impact on the image quality. This phenomenon becomes apparent in 3D imaging especially when observing a deep position of the three-dimensionally specimen, such as a tissue or organ model of the human body or animals. In principle, this happens because its observation depth and sample's characteristics effects on the light passing through it.
Along with optical technology being achieved over our long-established core competence, Olympus has been successful in developing the unique imaging technology that enables acquiring crisp and clear images even in the deep observation technique, by optically compensating the refractive index difference between the specimen and the oil immersion liquid where the light deterioration occurs.
Acquire crisp and clear images even in the deep observation by optically compensating the refractive index difference where the light deterioration occurs.
Clear cross-sectional images can be acquired by precisely controlling the amount of optical aberration correction according to the level of depth. A various type of three-dimensional image are reconstructed from these cross-sectional images. Implementing 3D imaging from the top to the deep bottom of target and time-lapse imaging together enable reconstructing complex structure as well as vital activities three-dimensionally within a live tissue or organ.
